と、この例外は絶えず繰り返されます。また、それは言う：私はadRequest.addTestDeviceしなければならないのはなぜ

が、AdMobの要求は（ない.setTesting（真）がないという意味）通常の方法で起動しましたか？
再び、エミュレータで正常に動作しますが、デバイスでは正常に動作しません。私は別のアンドロイドバージョン（2.2、2.3など、少なくとも5つの異なるバージョンがテストされている）とfroyo 2.2とHTC HD2と三星ギャラクシースピカを試してみました。その偽のリクエストでデバイスを溺死させ、広告を表示しない
なぜですか？

Answer 1

あなたの/ etc/hostsファイルは、r.admob.comを127.0.0.1に再定義しました。すべての広告をブロックするので、さまざまなソースからダウンロードしたカスタムROMがすべて行います。/etc/hostsファイルを編集して、そのエントリを取り出します。
